在給一個生產庫做災難恢復的過程中，recover database報錯
SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-16433: The database must be opened in read/write mode.
該庫無備份無歸檔，意外掉電，所以走到這步必須見招拆招的解決。
於是準備重建控制文件，以noresetlogs拉起數據庫
結果在mount狀態下，backup controlfile to trace也報錯ORA-16433
於是手動創建控制文件
1.archive log list檢查歸檔情況
2.select * from v$nls_parameters檢查字符集情況
3.SQL> select name from v$datafile order by file#;
SQL> select group#, member from v$logfile;
SQL> select name, bytes from v$tempfile order by file#;
確認各種文件location.
然後使用以下模版，隨便找個庫trace都可以，關鍵是注意標點符號（尤其是logfile與datafile的最後一行，沒有逗號）
CREATE CONTROLFILE REUSE DATABASE "TEST1" NORESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 292

控制文件成功創建，進入下一流程。
創建文件時標點不清楚會導致
ORA-00600 [kcfccfl_1] or ORA-00600 [kccccfl_1] or ORA-02236 when Creating Control File (文檔 ID 1434813.1)
ORA-01163: SIZE clause indicates string (blocks), but should match header string
Cause: The size specified in bytes in the SIZE clause of the CREATE CONTROLFILE statement does not equate to the number of blocks recorded in the header.
Action: Specify the correct filename and size ( in bytes ).
